HELP: Pre-processing to mask areas in strings TYPE: OBJECT SYNTAX: MASK(CHAR=ASTERISK/MINUS/DOT/X,CCSID='str',HEAD=num,TAIL=num,CHANGE=INNER/OUTER)
This object can be used to mask strings as pre-processing step. For this you can define the masking character (default is '*'), the character set, the start (6) and end points (4) and if the replacement is done for the inner or outer part.
The masking is not invertible. A post-processing step while writing cannot reproduce the original data.
NUMBER: CHAR=ASTERISK/MINUS/DOT/X - Masking character [ASTERISK]
ASTERISK - Asterisk also known as star (0x2A for ASCII/UTF, 0x5C for EBCDIC)MINUS - Minus sign (0x2D for ASCII/UTF, 0x60 for EBCDIC)DOT - Dot sign (0x2E for ASCII/UTF, 0x4B for EBCDIC)X - Small x sign (0x2E for ASCII/UTF, 0xA7 for EBCDIC)STRING: CCSID='str' - CCSID / Character encoding [auto]NUMBER: HEAD=num - Number of characters at the beginning [if TAIL then 0 else 6]NUMBER: TAIL=num - Number of characters at the end [if HEAD then 0 else 4]NUMBER: CHANGE=INNER/OUTER - Mask inner or outer part [INNER]
INNER - Mask inner partOUTER - Mask outer part
